Please don't send content free pings and please allow a reasonable time
for review.  People get busy, go on holiday, attend conferences and so 
on so unless there is some reason for urgency (like critical bug fixes)
please allow at least a couple of weeks for review.  Sending content
free pings just adds to the mail volume (if they are seen at all) and if 
something has gone wrong you'll have to resend the patches anyway.
